COOLING DEVICE FOR GLASS-DRAWING APPARATUS.

Application filed October 19, 1918.

T 0 (ZZZ whom it may concern.

Be it known that I, WALTER A. Jones, a citizen of the United States, residing at C0 lumbus, in the county of Franklin and State of Ohio, have invented new and useful Improvements in Cooling Devices for Glass- Drawing Apparatus, of which the following is a specification.

This invention is an improved device for cooling glass cylinders contiguous to the molten glass during the drawing operation.

I11 drawing glass cylinders it is well understood that the 1 drawing operation is greatly facilitated if the glass forming the cylinder, is more or less chilled immediately after leaving the molten bath, and many different types of cooling devices-have been produced for this purpose. Such devices as are now in general useare objectionable be cause of their cumbersomeness which makes them rather difficult to handle, involving considerable labor and loss of time in re, moving them and replacing them after each draw. One of the objects of the invention isto provide a water cooled ring of sectional constructionwhich may be readily placed into and removed from' operative position. A further object is to provide a top stone having means for supporting the cooling device, wherebythe latter may be raised or lowered with the top, stone. A further object is .to provide improved means whereby the device may be readily moved to an inoperative position when not required.

The invention will be hereinafter fully set forth and particularly pointed out in the Referring to the drawing,

clalms. V j In the accompanying drawing Figure l is a perspective view illustrating atopstone and a-water cooledring constructed in accordance with theinvention, the ring being in operativeposition. v Fig. 2 is a similar view, illustrating the ring moved to. inoperative position and the drawing opening closed. Fig. ,3 is a transverse sectional view. r

10 designates a top stoneof any suitable type, preferably constructed of refractory clay, and provided with the drawing opening 11. Secured to the top stone in suitable manner are hangers l2, each formed of uprights rigidlysecuredto-the top stone, and connected by a horizontal bar, said hangers being engaged by the hook portions'of the top stone suspension rods .13, suspended from any suit- Specification of Letters Patent.

able hoisting mechanism, not shown, but in a manner well understood in the art. The uprightportion of the hangers 12, are provlded with bearings 14, in which are mounted rock shafts having solid middle portions 5 and hollow end portions 16. The cooling ring consists of two, more or less, sections 17, two of such sections being illustrated and of semi-circular form. Said sections are formed with hollow bodies which communicate with the hollow portions 16 of the rock shaft, through hollow hinge members 18 the ends of which are attached to the sections 17 and the hollow shafts respectively, so that the sections 17 may b 20. In order to assist in the movement of 1 the ring sections 17, cables 21 are provided connected to the rings at 22, and bearin against antifriction rollers 23, carried by the hangers 12. Said cables are provided with counterweights 24, and work upon sheaves 25 supported in an elevated position.

Cooperating with the top stone 10, is a refractory clay anchor or ring 26, which may be of any well known'construction, the same being provided with a flange 27, which fits within the drawing opening 11. A refractory clay cover 28, is also provided to cover the drawing opening during the melting down of the aftermath, said cover being provided with hooks 29, engaged by suspension rods, whereby it may be handled in a manner well understood in the art.

In operation, when it is desired to draw a cylinder, the anchor 26 is brought in position beneath the top stone, and the latter lowered until the flange 27 enters the drawing opening 11, thereby holding the anchor in position. The sections 17 of the cooling ring are then lowered to the position illustrated in Fig. 1, whereupon the bait may be tion of the finished cylinder from the molten body may be brought about, the ring sections 17 are moved to the positions illus- If it is desired to draw of the cylinder relatively trated in Fig. 2.

positioned to be necks and caps of cylinders are I action may be i to one side and the thin with respect to the body of the cylinder, the ring sections 17 are not placed in the positions illustrated in Fig. 1 until the neck and cap have been formed, after which, and without interruption to the drawing process, the ring sections m y be placed in position to surround and cool the rest of the cylinder as it is being drawn. It will be understood, of course, that the cooling fluid is introduced through pipes 19 at one end of each rock shaft, and passes through the contiguous hollow portion 16 and hinge 18, into the section 17. after which it passes out through the other hinge member 18, hollow portion 16 and pipe 19.

From the foregoing it will be readily understood that by means of the invention the cooling effect produced may be so controlled that thenecks and caps of cylinders are formed ina manner which will permit of the working of the glass formed, which is a very important feature in the art of drawing glass cylinders, and the cooling device is capable of such control that after the cylinder has been drawn, the cooling eliminated in order that the walls of the cylinder at the juncture with the molten glass, may be drawn out very thin so thatthe burning off and separation of the finished cylinder from the molten body may be quickly accomplished. Another advantage lies in the construction and mounting of the cooling ring whereby the cooling sections may be moved to one side if thin cylinders are required. Another advantage lies in mounting the cooling device upon the top stone, whereby separate handling apparatus is not required to lift them independently, as is now common practice, whereby the cooling sections may be moved v refractory cover placed over the top stone during the reheating of the aftermath, the cooling ring being always maintained in operative juxtaposition with respect to the'opening in the topstone. Having thus explained the nature of the invention and described an operative manner of constructing and usin though without attempting to set forth all of the forms in which it may be made, or all of the forms of itsuse, what is claimed is 1. A cooling device of the-character described comprising a stationary support, a cooling ring vformed of complemental sections movably mounted upon-said support independently of each other, and means for supplying a cooling medium-to said sections. 2.
